Former Bernie Sanders supporters who sold out for Hillary Clinton (harsh, I know, but true) may want to do some soul searching following a new revelation from Goldman Sachs CEO Lloyd Blankfein. While not outright announcing he's voting for her next month, the way he praised her on "Fareed Zakaria GPS" suggests he's with her.

“I’m supportive of Hillary Clinton,” Blankfein said, according to a transcript provided by the network. “Yes, so flat out, yes, I do. That doesn’t say that I agree with all of her policies. I don’t. And that doesn’t say that I adopt everything that she’s done in her political career or has suggested that she might do going forward.”

Blankfein also praised the Democratic nominee's apparent willingness to engage with those sitting across the political aisle.

Of course, Sanders fans should bristle at Blankfein's praise for Clinton. The Vermont senator's impassioned criticism of Wall Street has been one reason he has attracted so many progressive fans. During the Democratic primary, he hammered Clinton for her lucrative Wall Street speeches and her refusal to release the transcripts. When she tried to claim she has stood up to the big banks at one of their debates, he mocked her.

“Secretary Clinton called them out,” countered Sanders. “Oh my gosh, they must have been really crushed by this. Was that before or after you received huge sums of money by giving speaking engagements?”

Additionally, new headlines reveal that donors are heavily financing Clinton's campaign. The Washington Times found that more than a fifth of the $1 billion donated to her was awarded by 100 well-to-do individuals and powerful labor unions.

Can progressive voters stomach the fact that people like Blankfein seem to want a Clinton win?
